I wonder how many of the 'other' ticking box people actually wrote following it: 'I do not have a gender, I have a biological sex which is x'.
Up to 136,000 of the 262,000?
Was the 116,000 really for people who actually wrote nothing, or does it include people who wrote things like "I don't believe in gender identities".
I find it hard to believe blank responses vastly outnumber "other" (18,000) responses there, so I think the 116,000 must include non-blank non-identity respones.
And in other places it says "no specific identity" for that category, so I think it may include the explicit refusals.
So I think the actual number of real gender people may be closer to 144,000 than 262,000.
